Abstract This paper presents a complex nonlinear finite element model of a full‐scale bridge deck that was experimentally studied under both pulsating and rolling load. The bridge deck was designed to incorporate three different reinforcement designs implemented at various portions of the slab to maximize test efficiency. The different stiffness across the longitudinal span poses a challenge for the finite element model to simulate the behavior of the bridge deck. The deck is comprised of zones incorporating different types of reinforcements, namely conventional steel rebar, glass fiber‐reinforced polymer (GFRP) rebar, and a new GFRP stay‐in‐place structural form system. All zones are integrated in one monolithic cast. The finite element model features characteristics such as nonlinear material laws, failure criteria, and interfacial relations for parts in contact. To verify the applicability and adequacy of selected material models, 14 specimens representing three different concrete structures and test setups from independent studies were modeled and validated. A model of the bridge deck was then created and validated using the data from the experiment featuring service load level.
